n8n-nodes-thanks-io
This repository contains the official thanks.io community node for n8n.
thanks.io provides everything you need for direct mail success, including AI-realistic handwritten postcards, letters, and notecards; QR tracking; delivery notifications; and powerful automation— all at super competitive pricing.
Installation
Follow the installation guide in the n8n community nodes documentation.
Credentials
You must have a thanks.io API key to use this node. You can register for a free account and obtain an API key here:
Once registered, generate a Personal Access Token in thanks.io:
- Dashboard → Settings → API Access
https://dashboard.thanks.io/profile/api
Then in n8n, create a credential named “Thanks.io API” and paste in your token.
Test Mode
thanks.io has a built-in API Testing Mode that accepts orders normally but automatically cancels them instead of sending real mail. Use it while building and validating your n8n workflow.
What it does:
- Accepts your API requests and validates your payloads
- Automatically cancels orders so no mail is physically sent
- Prevents accidental production sends during development
When to go live: Keep testing mode enabled until you have verified authentication is working, recipient payloads are correct, and creative/message fields render as expected. Then disable it to send real mail.
How to enable/disable: Visit Dashboard → Settings → API Access and toggle API/Zapier Test Mode.
Note: If testing mode is off, you have a one-hour window to cancel an order manually before it moves further into fulfillment.
